Preparing the Player for Playback
English
After turning it on, you may be able to play music files by
changing the input to USB. You can use ports other than the
USB-DAC port, but only one device will be detected if two or
more USB-DAC devices are connected.
The N5 has an Ethernet port that can connect a Network Audio Player directly. Using this port is recommended
for high quality audio playback. To play music files using a Network Audio Player, refer to the manual of the
player before playing. The N5 will be used as a NAS (network-attached storage) device.

changing the input to music server or network. You can also
use another player on the network rather than the player
connected to the player port.
